| Abstract: | The design features of the electron accelerator with a large-area 200-keV beam and results of its investigation are described. The accelerator is based on a set of discrete longitudinal filament cathodes and operates in the continuous mode. The cross section of the beam extracted into the atmosphere is 40 × 50 cm2, and the maximal current density of the extracted electron beam is up to 100 μA/cm2. The nonuniformity of the current density distribution over the electron beam cross section is 10% or less. |
